<div class="description"><div class="angular-equals-page"><p>Determines if two objects or two values are equivalent. Supports value types, regular expressions, arrays and
objects.</p>
<p>Two objects or values are considered equivalent if at least one of the following is true:</p>
<ul>
<li>Both objects or values pass <code>===</code> comparison.</li>
<li>Both objects or values are of the same type and all of their properties pass <code>===</code> comparison.</li>
<li>Both values are NaN. (In JavasScript, NaN == NaN =&gt; false. But we consider two NaN as equal)</li>
<li>Both values represent the same regular expression (In JavasScript,
/abc/ == /abc/ =&gt; false. But we consider two regular expressions as equal when their textual
representation matches).</li>
</ul>
<p>During a property comparison, properties of <code>function</code> type and properties with names
that begin with <code>$</code> are ignored.</p>
<p>Scope and DOMWindow objects are being compared only by identify (<code>===</code>).</p>
